The Greek acquiring market has consolidated aggressively since 2022. Four systemic banks each spun off or rebranded their acquiring arms, Viva emerged as the dominant SMB disruptor, and Worldline holds a large legacy POS book. For a Greek merchant in 2026, the question is which of these actually fits your business — not just which has the loudest pricing claim.
This is an independent breakdown of the six main acquirers active in Greece today.
Viva.com
Best fit: SMB retail, hospitality, restaurants, mobile/softPOS merchants, high-volume e-commerce
Viva has captured the SMB market with soft POS, integrated checkout, and transparent IC++ pricing at lower volumes than the banks will offer.
- Pricing: IC++ available from €10k/month; blended from 1.1% for SMB
- Settlement: Same-day to Viva account, T+1 to external bank
- Strengths: Modern APIs, soft POS on Android, strong Greek e-commerce integration, tap-to-phone
- Weaknesses: Support can be inconsistent at lower tiers; customer service is primarily digital
- Watch for: “IC++” quotes that still embed uplift on scheme fees — verify line by line
Worldline (ex-Cardlink)
Best fit: Large enterprise retail, chain POS deployments, legacy card-present merchants
Cardlink was absorbed into Worldline and remains the largest POS acquirer in Greece by terminal count.
- Pricing: IC++ standard above €50k/month; negotiable markups
- Settlement: T+1 to any Greek bank
- Strengths: Deep POS footprint, strong terminal uptime SLAs, pan-EU acquiring for multi-country chains
- Weaknesses: Slower on SMB onboarding, less competitive on sub-€30k/month volume, older portal UX
- Watch for: Terminal rental fees — often inflated on legacy Cardlink contracts
NBG Pay
Best fit: NBG banking customers, mid-market retail, merchants needing same-day settlement
NBG’s acquiring arm, now branded NBG Pay, competes directly on bank-integrated pricing and settlement.
- Pricing: Competitive for NBG current-account holders; standard for others
- Settlement: Same-day to NBG accounts
- Strengths: Tight integration with NBG business banking, Greek-language support, compliance simplicity
- Weaknesses: Less flexible on IC++ at sub-€40k/month, limited multi-currency
- Watch for: Blended rate defaults — ask for IC++ explicitly above €25k/month
Alpha Bank Acquiring
Best fit: Alpha Bank SMB customers, professional services, mid-market retail
Alpha acquiring is a competent mid-market offering, strongest for existing Alpha business customers.
- Pricing: Blended default, IC++ available on request at mid-market volumes
- Settlement: Same-day to Alpha, T+1 to others
- Strengths: Good customer service continuity with relationship manager, integrated lending
- Weaknesses: Less e-commerce depth than Viva or Worldline; slower on API feature velocity
Eurobank Merchant Services
Best fit: Eurobank customers, mid and large retail chains
Eurobank has rebuilt its acquiring offering with a stronger emphasis on chain retail and hospitality.
- Pricing: Competitive for existing Eurobank customers; benchmark externally otherwise
- Settlement: Same-day to Eurobank
- Strengths: Good chain-store support, solid reconciliation tooling, private-banking-grade service at the top end
- Weaknesses: Less aggressive on SMB pricing, limited soft POS compared to Viva
Piraeus Acquiring
Best fit: Piraeus banking customers, regional merchants, tourism-heavy businesses
Piraeus carries a large legacy merchant portfolio, especially outside Athens and in the islands.
- Pricing: Standard bank-linked, negotiable on volume
- Settlement: Same-day to Piraeus
- Strengths: Strong regional reach, good Greek-language support, decent hospitality and tourism vertical fit
- Weaknesses: Less modern technology stack, legacy contracts often carry high terminal rentals
The international PSPs
Beyond the Greek-domestic six, these international providers are active in Greece:
- Stripe — strongest for API-first e-commerce and SaaS
- Adyen — best for pan-EU multi-country enterprise
- Checkout.com — strong on conversion optimization for e-commerce
- Mollie — good SMB e-commerce option
- Revolut Business — competitive for SMB multi-currency
These generally offer the best transparent IC++ pricing but do not always authorize Greek-issued cards as well as local acquirers (2–4 percentage point gap on edge cases).
Fee benchmarks by merchant profile (Greece, 2026)
| Merchant profile | Typical winner | Typical effective rate |
|---|---|---|
| SMB retail, €5k–€25k/month | Viva or bank of primary account | 1.1%–1.6% |
| Mid-market retail, €30k–€150k/month | Viva, Worldline, or bank with IC++ | 0.75%–1.15% |
| E-commerce, EU cross-border | Stripe, Checkout, Adyen | 0.85%–1.25% |
| Enterprise chain, €500k+/month | Worldline or multi-acquirer setup | 0.55%–0.85% |
| Hospitality / tourism island | Piraeus or Viva for softPOS | 0.9%–1.3% |
Multi-acquiring: the underrated Greek strategy
For merchants above €200k/month, splitting volume between two acquirers (typically one Greek for domestic card authorization and one international for cross-border and EUR-denominated e-commerce) routinely saves another 12–20% on top of single-provider optimization.
This is standard practice for serious Greek e-commerce and hospitality operators.
What to ask every Greek acquirer before signing
- Is this IC++ or blended? — demand IC++ above €25k/month
- Line-by-line scheme fees — Greek acquirers sometimes uplift Visa/MC fees silently
- Terminal rental / gateway fees — historically inflated in the Greek market
- Authorization rate commitments in writing
- Settlement timing to your specific bank
- Early-termination fees — long contracts are a red flag
- myDATA / AADE compliance — how do they handle reporting integration?
The bottom line
No single Greek acquirer dominates across merchant profiles. Viva wins on SMB and modern tooling, Worldline on enterprise POS, the bank acquirers on settlement and relationship depth, international PSPs on cross-border e-commerce.
The merchants who overpay in Greece are consistently the ones who:
- Defaulted to their own bank without benchmarking
- Never renegotiated after a volume increase
- Missed the multi-acquiring opportunity above €200k/month
